Join our resident astronomers on Facebook Live every Saturday evening live from Chabot’s Observation deck! Each week, our astronomers will guide us through spectacular night sky viewing through Nellie, Chabot‘s most powerful telescope. Weather permitting, we will be able to view objects live through the telescopes and our astronomers will be available for an open forum for all of your most pressing astronomy questions. About Nellie Nellie is a 36-inch reflector telescope, housed in a rolling roof observatory that allows access to 180 degrees of sky. This modern, research-quality telescope offers breathtaking views of the cosmos.
